really great point, we probably got a bit too enthused about having multiple sound effects that you can spam, but even internally we haven't been able to get a perfect score, and we have some pretty cracked out osu players :P
limiting it down to fewer buttons (and doing some more work to make the sequences easier to interpret) & giving the spinner more love so you dont need to be so careful about where you start your spin would definitely make the game play a lot better - i guess that's the hard part of a gamejam however, it's all tradeoffs...
thank you for playing and the kind words, we really appreciate it :) !!!
